    Unknown leaking in 2021 expedition

    The fan only cooling works great. Completely adequate, and never leaks. The rear seats have no ventilation, so double NO for that as a possible cause. I liked the headliner/paper towel idea. Just out of curiosity, is your AC drain letting water out when your AC is running?

    Can fumoto valve cause oil pressure issue like dealer claimed?

    I’m in the “No possible way” a Fumoto valve caused an oil pressure problem. I have been using them for 10 years with no issues. When I first started using them I read about possible remnant oil left in the pan, so after draining the oil I pulled the valve to see how much was still in there...

    Yes to eLSD or No to eLSD on our next Expedition

    We have a 2018, and this was included with the HD tow package then. I have only used it a couple of times, but it worked very well. Nice to know it's there. If I could I would issue a TSB warning of making sure the wife is aware NOT to set her purse in the middle on the console. This can...

    Possible Transmission Issue !! NEED HELP

    You mentioned "100" mph. Any chance you hit the speed limiter at 102 mph? I, of course, have only heard of this happening, and have never experienced it myself.

    WeatherTech Mud Flaps On

    Installed black WT a couple of years ago. Stock tires. Mild off-roading, backed through some 3 foot wet/heavy snow drifts, no problems. Easy install. They do the job for me.

    Gas Mileage with Heavy Duty Tow Package?

    This is almost exactly what I have seen. Strictly city, at 3 to 4 mile trips at a time, we are getting about 14. Towing, it doesn’t do much better than my 2003 Expedition did, but it does it so much easier.

    Disappointing 4WD performance on snow.

    This is not a conspiracy theory, or a secret. Just look at the UTQG rating on the stock tire. My STOCK Toyo Open Country UTQG rating is 300, marked right on the tire. VERY low rating. Same low rating on all of my original tires since 1991. 300-360.

    Disappointing 4WD performance on snow.

    Great thread! I have several things to comment on. We bought a private party 1999 Explorer in 2003. They didn’t even know it had low range. It took a few times in and out before it worked properly. A high percentage of people just don’t need it. ALL of our original tires over the last two...

    Deep sleep mode

    Have a load test done on your battery. That is the most likely cause, a weak battery.

    10 Speed Transmission - Opinions

    We own a 2018 Limited, 10/18 build date, replaced a 2003 Eddie Bauer. LOVE the 10 speed. I keep the gear notification display on always. It shifts perfectly, and we have not noticed an objectionable delay R to D. We get about 20% better fuel economy, on average. Towing is superb, but I wish...

    For Those Who Don't Think a Catch Can is Needed on Gen 4 s...

    Well, no, but it’s the same idea. I think yours looks better! My objective was to get the engine cover to be in the same position that it was in prior to the catch can installation. I ran the PCV tube forward, toward the radiator. It seem to clear everything underneath the engine cover, but as...

    For Those Who Don't Think a Catch Can is Needed on Gen 4 s...

    After much study, I decided to go with the JLT for my 2018. She only has 7500 miles, so hopefully I caught it early enough. She will be in our family until she crumbles into dust, so my rationale is that at worst I will keep my intake cleaner for no reason. At best I could save a couple of head...

    What is the purpose of the flip-up tailgate window?

    Good Golly! One of our FAVORITE features. We use it consistently, for reasons mentioned previously, and also for backing in the boat when one of us is in the boat. Visual + oral communication enhancer!! We previously had a 2003 EB 5.4. When we picked up our 2018 we spent over an hour during...

    Items for inspection

    I took a chance once, and bought a vehicle site unseen. There were a lot of pictures and it passed an inspection. When it was delivered on the flatbed I checked the oil and it did not touch the dipstick. My heart sank. Turns out it was a cold start, but it was still 2 quarts low out of 4.5...

    Buying a used ford expedition and most do not have HD tow package can one be installed aftermarket?

    There is an easy way to convert a 4th Gen if you don’t have the tow package. Simply trade it in for one that has it. WAY cheaper!! We were very surprised when we started looking for a replacement for our 2003 in early 2019. We wanted a 2014-16, but we made the mistake of test driving a 2018...

    Gas mileage

    2018 Limited, coming from a 2003 5.4. Towing and aggressive driving delivers similar mileage. 3.5 eco has better acceleration and tows easier. It is way more “fun” to drive. The big difference is with conservative driving we can get some great economy. Keep your foot out of it and don’t speed...

    Autostopeliminator

    Installed mine today. 20 minutes. I didn’t see where the video showed to tuck the device through the slot. The instructions showed it though. Took a drive with the wife. Let her drive. She had no idea why I did the evil laugh every time we stopped. A Snidley Whiplash feeling for sure. We’ll...

    Autostopeliminator

    We bought our 2018 Limited in January of 2019. Planning on keeping her 20 years+, so we didn’t care she was technically a year old. I couldn’t believe anyone would pay close to $100 so you didn’t have to push one button. How silly!! After almost 1.5 years of ownership, and constantly...

    4th gen common issues?

    Own 18 Ltd. We have had the mirror issue, but never addressed it. We had the HVAC go crazy, blowing hot air when cold was selected, blowing panel or upper when floor was selected, etc. replace control board and no issues since. The biggest problem is that since we can haul seven people we always...

    Impact of Heavy Duty Tow Package (w/ 3.73 axle ratio) on MPG gas mileage

    We have the tow package, non max. Towed a 2k lb 4 Wheeler trailer 500 miles. 1st leg, slight crosswind 5mph, 40 degrees 65 mph got 19. I really bragged her up!! My ‘03 Expy never broke 14 mpg with that trailer... Trip home, 13 degrees with 30-40 mph headwind, got 9.5 mpg w/91 premium. I didn’t...

    LED Headlights- Unexpected “negative”

    We were going to get an XLT, but we made a mistake on our test drive. We drove a Limited with LED headlights. They are WAY better!! Even with this unexpected negative. That was one of the main reasons we ended up with a Limited. NO regrets....

    LED Headlights- Unexpected “negative”

    We are just passing the one year mark Of ownership. Only had one issue, weird HVAC function with hot, cold, and panel/floor/defrost controls front and rear wigging out. Two trips to dealer, HVAC control board replacement. SOLVED. We love our Expedition, and have very few concerns, but here is...

    Press Stop Underway, Automatically Shifts to Park???

    Just a quick note, I was traveling at near highway speed’s when I realized I had not changed my mode to economy, which I usually do. I grabbed the knob while watching the display and nothing changed. To my horror I realized I had changed the shift knob to R. I quickly went back to D. Nothing...

    Auto stop benefit

    I would let this go, but your ignorance is confusing people. When an engine is shut off the oil pump stops. Oil drains back into the pan, pressure drops to zero. Some residual oil is left on the lubricating surfaces, and diminishes over time. Even a few seconds reduces the oil film protecting...
